Jackknife Repeated Replication - DRAFT VERSION

NAEP uses a jackknife repeated replication (JRR) procedure to estimate the sampling variability of all statistics presented in NAEP reports. This robust variance estimator takes into account sampling variability that arises due to the imprecision in the measurement of individual proficiencies as well as sampling variability resulting from the features of the sample design (stratification, clustering, and weighting).

NAEP uses the JK2 variant.
